Hi, I have updated my virtuemart 2.0.14 to version 2.0.16. After updating when I click on a product in order to view the product details it show the error: 404 the requested product does not exist. What is the problem? I have checked almost everything by I'm not able to find a solution. I also updated from 2.0.14 to 2.0.18a but I got the same error. Please help me...

I don't think so. I have another site with the same configuration and the version 2.0.18a is working with no problem. The version 2.0.14 worked with no problem. What changed after vm update to 2.0.16 and the product page does not open? I checked the link that appears on the bottom left corner of the screen when I set the mouse over the product link in category page, and the link is OK. It's exactlly the same like before. So what has changed and it doesn't work?
